BOTTLE-INDICATOR.

Specification of Letters Patent.

Patented Jan. 27, 1914.

Application filed November 19, 1912. Serial No. 732,396.

To all whom it may concern Be it known that I, PATRICK FLYNN, a subject of the King of Great Britain, residing at Big Creek, (care of Stone & Webster Construction Company,) in the county of Fresno and State of California, have invented new and useful Improvements in Bot-- tle-Indicators, of which the following is a specification.

An object of the invention is to provide an indicator for bottles adapted to contain fluids, in which indication will be made when fluid is withdrawn from the bottle so that if the bottle is refilled with a spurious fluid which is intended to deceive the user, the person using the fluid can readily perceive that the new fluid in the bottle has been placed therein to supplant the original contents of the bottle.

The invention embodies, among other features, a float movable, in a tube provided with a series of baffles and which is arranged within a bottle so that when a portion of the original contents of the bottle is withdrawn therefrom, the float will descend with the fluid and will be prevented from moving upwardly in the tube if the bottle is refilled with a fluid, thus disclosing to the user whether the bottle contains the original contents or has been refilled with some other fluid.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure 1 is a vertical sectional view of a bottle, showing my device applied thereto; Fig. 2 is a horizontal sectional view of the bottle, taken on the line 2-2 in Fig. 1; and Fig. 3 is a perspective view of the float.

Referring more particularly to the views, I disclose a bottle 10 provided with the usual filling opening 11 normally closed by a cork or stopper 12, a tube 13 being arranged within the bottle 10 with the upper end of the tube projecting exteriorly of the bottle and adapted to be normally sealed by a sealing member 14.

A series of bafiies 15 project from a wall of the tube 13, within the same, to form a series of superimposed compartments 16, the said baffles having inclined faces 17 and arranged in pairs within the tube 13, as shown,

the lower ends of the baffles 15 being larger thanthe upper ends thereof in view of the inclination of the faces of the baflies, thus forming restricted entrances 18 between the compartments 16.

A float 19 is provided and is preferably made of glass and provided adjacent one end thereof with a weight 20 of any suitable nature, the said float being adapted to read ily slide downwardly down the inclined faces 17 of the bafiies 15 from one compartment 16 into the next lower compartment in the tube 13, but when the float is buoyed upon the surface of a fluid in the tube 13, the float, in view of the position of the weight 20, will assume a position inclined to the vertical plane of the tube, thus preventing the float 19 from moving upwardly from one compartment to the next in View of the restricted entrances 18.

In the use of the device, the bottle 10 is first filled with the desired fluid and, as will be readily understood, the fluid will also rise in the tube 13 to the same level as the fluid in the bottle. Now after the filling opening 11 has been sealed, the float 19 is dropped into the tube 13 and will float upon the surface of the fluid in the tube, after which the tube 13 is closed by the sealing member 14. Now when the contents or any portion of the contents of the bottle 10 is removed therefrom by pouring the same through the opening 11 therein after the stopper 12 has been removed, the weight 20 will descend in the tube from one compartment 16 to the next lower compartment, it being readily understood that the weight will descend in the bottle in accordance with the amount of fluid in the bottle, that is to say, if a certain amount of fluid is withdrawn from the bottle in the usual manner the depth of the fluid in the bottle will be less and consequently the weight 20 will descend within the tube and float upon the surface of the fluid therein so that the height of the weight in the tube will be the depth of the fluid in the bottle, it being further seen that in view of the particular arrangement of the weight 20 relatively to the baffles 15, and in an inclined position relatively to the baffles 15, thus supporting the weight in an inclined position relatively to the vertical plane of the tube, the said weight will readily slide down the inclined faces 17 of the baifles 15 and descend in the tube with the decrease of depth of the fluid therein. Now if a spurious, adulterated or other fluid is poured into the bottle, the float 19 will tend to rise and seek the level of the then contained fluid in the bottle. The arrangement of the baflies 15, however, and the inclination of the float 19 relatively thereto, will prevent the passage of the float through the restricted entrance 18 and therefore the float will be prevented from passing upwardly in the tube 13. It will now be seen that regardless of the additional fluid that is placed within the bottle, the position of the float 19 in one of the compartments 16 will disclose to the user the depth of the original fluid that had been initially placed within the bottle, and if the depth of the fluid in the bottle is greater than the height of the float therein, the user will readily perceive that the original contents of the bottle has been either adulterated or a spurious fluid has been substituted therefor. If desirable, suitable graduations 21 can be marked upon the tube 13 in the horizontal plane of the battles 15 therein, thus enabling the user to more readily perceive the difference between the height of the float in the tube and the depth of the liquid in the tube and bottle, when the bottle is filled or partially refilled with a fluid after portions of the original contents of the bottle have been withdrawn. Having thus described my invention, I claim: i

In a device of the class described, the combination with a bottle adapted to contain a fluid, of a tube in the said bottle and adapted to receive a portion of the fluid contained in V the bottle, with the depth of the fluid in the tube registering with the depth of the fluid in the bottle, battles in the tube and spaced apart to form compartments therein, with restricted passages connecting the said compartments, a float in the said tube and adapted to float upon the surface of the fluid in the tube and in one of the said compartments therein, and a weight contained within the said float and loosely movable therein to normally retain the float in an inclined position and prevent the same from passing upwardly from a lower compartment to a higher compartment in the tube.

In testimony whereof I aflix my signature in presence of two witnesses.
